Application flied January 20, 1813. Serial No. 743,182.

To all whom it may concern "Be it known that I, HARRY M. THAYER, a citizen of the United States, residing at Woodhull, in the county of Henry and State 1 of Illinois, have invented certain new and; useful Improvements in Sectional RoofGon-' struction for Silos, of which the following is a specification.

The present invention relates to certaln' new-and useful improvements in roof constructions such as are adapted to be embecomes necessary or desirable.

A further object of the inventionpis to provide a roof of this character wh1ch 1s comparatively simple and inexpensive 1n its construction, which can be readily mounted upon the silo or other structure, and which can be easily .moved into either an open on a closed position.

ed out in the appended claims.

For a full understanding ofthe invention, reference is 'to be had to the followlng description and accompanying drawings, in which tion of a silo provided with a roof constructed in accordance with the inventlon, the said roof being shown in a closed pos1-' tion. Fig. 2 is a similar view showing the roof in an open position, the roof plate being removed from one of the roof sections to show the manner of constructing the frame thereof. Fig. 3 is an interior view of a portion of the roof, showing the position assumed by the parts when the roof is in a closed position. 4 is a similar view with the roof sections swung upwardly into an open position. 'Fig. 5 is a horizontal sectional view on the line 55 of Fig. 4. Fig.

6 is an enlarged detail view of one of the supporting brackets or castin s and a portion of one of the roof sections, the said roof section being shown by full 'lines in the position assumed when ina closed posi-' tion, and by dotted lines in the position assumed when swung upwardly into an open position. 'Fig. 7 is a similar view of the oppo'site side of the supportin bracket or casting, showing a portion 0 an adjacent roof section, the said roof section being shown by "-full'lines in the position assumed when closed, and the positions of the two adjacent roof sections when 'in a raised posit-ion being indicated "by dotted lines, and Figs. 8 and9 are detail perspective views ofa pair of=the-supporting brackets or castinigzs which are constructed in rights and Corresponding and like parts are referred to=in=the following description and indicated in all the views-o the drawings by the same reference characters.

Specifically describing the present embodiment of the invention, the numeral 1 designates the upper portion of a silo or similar structure upon which it may be desired to mount the roof, the said silo having a substantiallycircular top. The roof has a substantially conical format-ion when closed, and comprises an annular series of With these and other objects in view, the. invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointtriangular frame upon which the roof plate 2 is mounted. As indicated upon the drawings these triangular frames comprise the upwardly converging side pieces 3 which f are connected at intermediate points in their Figure 1 is a perspectlve view of a porlengt-hs by the transverse cross bars 4. The roof plates 2 are preferably formed in the two triangular sections 2 and 2, the edges of the sections overlapping at the center of the roof section and being riveted or otherwise connected to provide a seam '5. These longitudinal seams!) serve to "reinforce the roofing plates '2 at the center thereof.

The various roof sections A and B are mounted upon the supporting brackets 6 which are a lied "to the upper edge of the silo 1. Each of these supporting brackets -6 is shown as comprising a substantially vertically disposed base portion 6f which is adapted to be fitted against and firmly connected'to the inner face of the silo at the top thereof, and also with an upwardly and inwardly inclined seat 6* upon which the roof sections A and B rest when in a closed .position, the said seat 6 and base portion 6 being connected b" the reinforcin web 6. It will also be 0 served that ace of the Speciflcationnfletters Patent. t t D3039, 1913 out by Fig. 5.

supporting brackets 6 is formed with a pair of outwardly projecting arms or wings 6 .and 6 between which the side pieces 3 of the pivot arms 6 and. 6 are formed in ri hts and lefts, as indicated by Figs. 8 an 9, and the various supportin brackets are designed to be applied to t e top of the silo in an annular series so that the shortlarms 6 and long arms 6* of adjacent brackets will face each other. The side pieces 3 of the roof sections A are designed to be pivoted uponthe short arms 6 of the supporting brackets 6' in some suitable manner as by means of the pivot bolts 7, while the side pieces 3 of the alternate roof sections B are esigned to be pivoted upon the longarms 6in some suitable manner as by means of the pivot bolts 8. It will thus beobvious that the pivot points of the roof sections B are disposed in a circle which is concentric with but somewhat larger than the circle in which the pivot points of the alternate roof sections A are disposed. In other words, the ivot points 8 of the roof sections B are disposed outwardly farther away from the center of the silo than the pivot points 7 of the alternate roof sections A. Owing to this manner. of pivoting the roofsections A and B, 'all of the various roof sections can be swung upwardly into a substantially vertical position, as indicated by- Figs. 2 and 4, the roof sections A which are pivoted uponthe short arms 6 being swlmg upwardly first and the alternate roof sections B which are pivoted upon the lon arms 6 being subsequently swung upwar In a reverse manner, when closing the roof, the roof sections B would first be swung inwardly and the roof sections A subseuently swung inwardly, all of the roof sect ons then cooperating with each other to produce a conical roof, as indicated by Figs. 1 and 3.

When the roof sections A and B. are swung upwardly into a substantiall vertical position, it will be observed t at adjacent roof sections are slightly ofiset from each other, this feature being clearly brought This is a very important feature of the invention, since otherwise the lower corners of the triangular roof sections would interfere with each other and prevent the roof sections from being swung upwardly. The invention also contemplates means for locking the various roof sections A and B in an upright or open position. For this purpose a series of tie rods 9 are provided, one end of each of the tie rods being loosely connected at 10 to the edge portion of ,one of the roof sections and being provided at its free end with a hook member 11 which is adapted to engage a keeper 12 upon the adjacent roof section. When these tie rods 9 are placed in operative position, as indicated. by Fig. 4, the various roof sections A and B are securely locked together and retained in an upright or open position. When the roof sections are swung inwardly into a closed position these tie rods 9 hang loosely, as indicated by Fig. 3. It will be observed by reference to Fig. 4 that projecting kee er guards 12 may be located on the mo sections adjacent the keeper 12 to act as abutments to prevent the hooked ends of the rods 9 from slipping through and past the keepers.

Having thus described the'invention, what I claim as new and desire to secure by Letters Patent, is

1. A roof construction including an annular series of triangular roof sections hingedinward from their eaves ends so as toswing upwardly into an open position, alternate roof sections being mounted to swing about different centers so as to be oflset from each other when swung 'upwardly.

2.. A substantially conical roof including an annular series of complemental triangular roof sections, and S11 porting brackets adapted to. be applied to t e structure upon which the roof is mounted, the said roof sections being pivotally mounted inward from their eaves ends'upon the supporting brackets so as to be swung upwardly into an 0 en ition and the said supporting brac ets ing formedfwith seats upon which the roof sections rest when swung inwardly intoa closed position.

3. A substantially conical roof including an annular series of complemental roof sections, and a series of supporting brackets adapted to be a plied to the structure u on which the mo is mounted, the brac ets being each formed with-a long arm and-a short arm, and alternate roof sections being pivotally mounted upon the short arms, while intermediate roof sections are pivotally mounted upon the long arms, the various roof sections being adapted to be swung upwardly on pivots located inward from their eaves ends into an open position and adjacent roof sections being then offset from each other. j

4. A substantially conical roof .including an annular series of complemental triangular roof sections, and a series of su porting brackets adapted to be applied to t e structure upon w 'ch the-roof is mounted, each of the brackets being formed with a seat upon whichthe roof sections rest when s inwardl into a closed position and with means or pivotally engagin the roof sections, adjacent roof sections being mounted to swing on pivots located inward from their eaves ends and about different centers so as to be offset from each other when swung upwardly into an open position.

5. Asubstantially conical roof including an annular series of complemental triangula;' roof sections, and a series of supporting brackets adapted to be applied to-the structure upon which the roof'is mounted, said brackets being each formed with a seat upon which the roof sections rest when swung inwardl into a closed position and being also each ormed with a long arm and a short arm, alternate roof sections bein pivotally mounted upon the long arms of t e brackets while the intermediate roof sections are pivotally mounted upon the short arms of the brackets so that adjacent roof sections will be offset from each other when the roof sections are swung upwardly into an open position on pivots located inward from their eaves ends 6. A substantially con cal roof including an annular series of oomplenientalv triangular roof sections, and a series of suppo brackets adapted to be applied to the structure upon which the roof is mounted, the

located inward fromtheir eaves ends, and

alternate roof sections being then ofiset from each other.
